You're talking apples and oranges here. Your processor is only going to run as fast as your motherboard will let it. And your RAM will only operate as fast as your processor will let it (if that is the limiting factor). Do yourself a favor and upgrade your mobo when you upgrade your processor (unless you did, and in that case, maybe you should read a little more before making your purchases).

Umm... actually, I do know and I answered your question. Your motherboard is the limiting factor and most likely YES, (if you need me to spell it out) it will most likely run slower than if you had compatible hardware.

There really isn't a point of getting anything more than PC2700 if you have less than an Athlon XP3200+, because the FSB on those processors is only 333MHz, so you won't gain any performance, in fact you might lose some because the RAM and the processor are operating asynchronously.

Naturally I didn't feel inspired enough to read all the links for you, since I already slaved away for long hours under a blistering sun pressing the search button after typing four whole words! - Quzah
